My current rig is seven years old. Alone the way I did some upgrades but it is definitely showing its age. Right now I get my QX9650 running at 4G stable on air. I have 8gigs of DDR21000 RAM and a slightly OCed 5870. It is a good PC but it simply cannot perform well in newer titles with high resolution. So I've been thinking about this. I got two options. Option 1: Push the QX9650 as high as it can go and be settled with the performance. Get a 7870LE for graphic upgrade and wait until all the other parts start to fail. Option 2: Save up for a while, build a new Haswell based new rig and sell my old pc to cover the expense. The new rig will definitely perform better and has better energy efficiency. What do you guys think? Do you think the QX9650 can be pushed above 4G, say 4.5 on air? Is it gonna worth it?
